Abstract

Procédé de fabrication de nanoparticules d'au moins un oxyde de métal de transition choisi parmi Ti, Zr, Hf, V, Nb et Ta enrobées de carbone amorphe, le procédé comprenant les étapes successives suivantes : (i) un mélange liquide contenant en tant que précurseurs au moins un alkoxyde du métal de transition, un alcool, de l'acide acétique en excès vis à vis du métal de transition est préparé puis dilué dans de l'eau afin de former une solution aqueuse, les précurseurs étant présents dans la solution aqueuse selon un rapport molaire tel qu'il prévient ou limite suffisamment la formation d'un sol pour que la solution aqueuse soit lyophilisable et tel que le métal de transition, le carbone et l'oxygène sont présents selon le rapport stœchiométrique dans lequel ils se trouvent dans les nanoparticules, (ii) la solution aqueuse est soumise à une lyophilisation, (iii) le lyophilisât obtenu à l'étape précédente est pyrolyse sous vide ou sous atmosphère inerte afin d'obtenir les nanoparticules. L'invention concerne également l'application du procédé à la fabrication de carbure de métal de transition.
